An electric tool is provided which enables preventing adherence to a rotor core of dust, such as iron powder, that has entered a motor. The electric tool includes a cylindrical motor housing 10 accommodating and supporting the motor, and a cooling fan attached to a rotation shaft of the motor, and cools the motor by flowing air generated by the cooling fan toward the back or front of the motor housing 10, wherein a fan guide 50 guiding cooling air is provided in front of an insulator 35 of a stator 30 of the motor. The fan guide 50 includes a first cylindrical part 51 which covers a rotation space of the cooling fan, a guide surface 53, and a second cylinder 55 which extends backward from the guide surface 53, wherein a labyrinth space 39 is formed by the insulator 35 and the second cylinder 55. By providing the labyrinth space 39, it is possible to block the flow of cooling air from the outer peripheral side of the stator 30 to an opening 53a.
